Note: The 468-979 is the "Interchangeable Type" of the Digimatic Bore Gage Sets. Only one electronic readout is included in the set and users have to interchange the heads on the electronic readout to cover the full range of the bore gage. Users must recalibrate the Digimatic Holtest in a setting ring once one of the heads has been swapped out. The Digimatic Holtest Three Point Micrometers could be called the most popular electronic internal micrometer. Customers have learned that Mitutoyo offers products of the best of quality and the 468 series of bore gages speaks for itself. The Digimatic Holtest sets are accurate, repeatable, and have user-friendly electronics.
